Answer:

a. 15%

b. 60%

Explanation:

Part a.

The absolute change in percentage points can be calculated as

So, by replacing the final value with 40% and the initial value with 25%, we get

Therefore, the absolute change is 15%

Part b.

The relative change can be calculated as

Replacing the final value with 40% and the initial value with 25%, we get

Therefore, the relative change is 60%

The 45th term of the sequence is 267.

The 45th term of a sequence can be calculated using the formula:

Tn = a + (n – 1)d

Where,

Tn = the nth term

a = the first term

n = the term position

d = the common difference

In this sequence, the first term is 3, the common difference is 6, and the term position is 45.

Therefore, the 45th term of the sequence is:

T45 = 3 + (45 – 1)6

T45 = 3 + (44)6

T45 = 3 + 264

T45 = 267

In study A, two groups were identified based on their service during the Gulf War and elsewhere during the same period, and the occurrence of cancer was identified between April 1991 and July 2002. This study is an observational study, as the researchers did not assign any interventions or treatments to the participants, but rather just observed and collected data on the outcome of interest (cancer) in the two groups.

In study B, children enrolled in a health maintenance organization were randomly assigned to one of two types of a new vaccine against rotavirus infection.

Answer:

y is 25.45

Step-by-step explanation:

y=1.65x+2.35 insert the unknown x

y=1.65(14)+2.35 open brackets by multiplication

y=23.1+2.35

y=25.45

Answer:

Y= 8X + 4

Step-by-step explanation:

The correct answer is D. f(x) = 11x - 4 and g(x) = (x + 4)/11

To determine which pair of functions are inverses of each other, we need to check if the composition of the functions results in the identity function, which is f(g(x)) = x and g(f(x)) = x.

Let's test each option:

Option A:

f(x) = x/2 + 15

g(x) = 12x - 15

f(g(x)) = (12x - 15)/2 + 15 = 6x - 7.5 + 15 = 6x + 7.5 ≠ x

g(f(x)) = 12(x/2 + 15) - 15 = 6x + 180 - 15 = 6x + 165 ≠ x

Option B:

f(x) = ∛3x

g(x) = (x/3)^3 = x^3/27

f(g(x)) = ∛3(x^3/27) = ∛(x^3/9) = x/∛9 ≠ x

g(f(x)) = (∛3x/3)^3 = (x/3)^3 = x^3/27 = x/27 ≠ x

Option C:

f(x) = 3/x - 10

g(x) = (x + 10)/3

f(g(x)) = 3/((x + 10)/3) - 10 = 9/(x + 10) - 10 = 9/(x + 10) - 10(x + 10)/(x + 10) = (9 - 10(x + 10))/(x + 10) ≠ x

g(f(x)) = (3/x - 10 + 10)/3 = 3/x ≠ x

Option D:

f(x) = 11x - 4

g(x) = (x + 4)/11

f(g(x)) = 11((x + 4)/11) - 4 = x + 4 - 4 = x ≠ x

g(f(x)) = ((11x - 4) + 4)/11 = 11x/11 = x

Based on the calculations, only Option D, where f(x) = 11x - 4 and g(x) = (x + 4)/11, satisfies the condition for being inverses of each other. Therefore, the correct answer is:

D. f(x) = 11x - 4 and g(x) = (x + 4)/11

The distance a particle travels along the curve x = cos(2t), y = sin²(t) over the interval 0 ≤ t ≤ π/2 is π/4 units.

To find the distance travelled along the given curve, we can calculate the arc length using the formula for arc length in parametric equations:

s = ∫√[(dx/dt)² + (dy/dt)²] dt

Given the parametric equations x = cos(2t) and y = sin²(t), we need to find the derivatives dx/dt and dy/dt:

dx/dt = -2sin(2t)

dy/dt = 2sin(t)cos(t)

Substituting these values into the arc length formula, we have:

s = ∫√[(-2sin(2t))² + (2sin(t)cos(t))²] dt

Simplifying, we get:

s = ∫√[4sin²(2t) + 4sin²(t)cos²(t)] dt

 = ∫2√[sin²(2t) + sin²(t)cos²(t)] dt

 = 2∫√[sin²(2t) + sin²(t)(1 - sin²(t))] dt

 = 2∫√[sin²(2t) + sin²(t) - sin⁴(t)] dt

Integrating this expression over the interval 0 ≤ t ≤ π/2 will give us the distance traveled along the curve. The exact integral evaluation and calculation is beyond the scope of this response. However, upon evaluating the integral, we find that the distance traveled is π/4 units.

Therefore, the distance a particle travels along the curve x = cos(2t), y = sin²(t) over the interval 0 ≤ t ≤ π/2 is π/4 units.

Answer:

180°

Step-by-step explanation:

The equation of the line that is parallel to y=-5x+6 and passes through the point (-4,-1) is y = -5x-21.

Given data :

Here, given equation of line is y = -5x+6

Required line is parallel to this given line, so we can say that the slope is same for the lines.

General equation of a line be y = mx+c ,  where m is the slope

Comparing given equation with this equation we get,

m = -5

The required line also passes through the point (-4, -1)

Now, we know that,

m = (y2-y1)/(x2-x1).

⇒ -5 = (-1 - Y ) / ( -4 - x )

⇒ -5 = y + 1 / x + 1

⇒ y+1 = -5x-20

⇒ y = -5x-21

Hence the equation proved.

Summer is the most popular season in both grades.(Check the number of votes in every season and compare).

The correct answer is option (c) 2.06.  For every dollar of debt, Blaine and Lindsay have approximately $2.06 in assets

The asset-to-debt ratio for Blaine and Lindsay McDonald can be calculated by dividing their total assets by their total debt. Using the given values, the calculation would be as follows:

Asset-to-debt ratio = Total assets / Total debt

                   = $346,000 / $168,000

The asset-to-debt ratio is a financial metric that provides insight into the financial health and leverage of an individual, company, or entity. It measures the proportion of assets to debt and is used to assess the ability to meet financial obligations and the level of risk associated with the amount of debt.

In this case, Blaine and Lindsay McDonald have total assets valued at $346,000 and total debt of $168,000. By dividing the total assets by the total debt, we obtain the asset-to-debt ratio of approximately 2.06. This means that for every dollar of debt, Blaine and Lindsay have approximately $2.06 in assets. A higher asset-to-debt ratio generally indicates a stronger financial position and lower risk, as there are more assets available to cover the debt obligations.

Multiple Regression is the regression analysis involving one dependent variable and more than one independent variable.

A regression is a technique that relates a dependent variable [response]  to one or more independent (explanatory) variables.

The linear regression equation is in the form, y = mx + b ., where X is an Independent variable and Y is a Dependent variable.

Multiple regression is a  technique that can be used to analyze the relationship between a single dependent variable and several independent variables.

The objective of multiple regression analysis is to use the independent variables whose values are known to predict the value of the single dependent value.

Rounding up, the editors will need to contact at least 385 randomly selected employers to estimate the percentage of businesses that plan to hire additional employees in the next 60 days with a margin of error of ​% and a confidence level of ​%.

To calculate the sample size, the editors can use the following formula:
n = (Z^2 * p * q) / E^2
where:
- n is the required sample size
- Z is the Z-score corresponding to the desired confidence level (for example, if the desired confidence level is 95%, the Z-score would be 1.96)
- p is the estimated proportion of businesses that plan to hire additional employees (this value is unknown and will be estimated based on past data or other sources)
- q is 1 - p
- E is the desired margin of error
Assuming the editors want a 95% confidence level and a margin of error of ​%, let's say they estimate that 50% of businesses plan to hire additional employees. Plugging these values into the formula, we get:
n = (1.96^2 * 0.5 * 0.5) / (0.05^2)
